Giant rectification in segmented, strongly interacting, spin chains despite the presence of perturbations
Kang Hao Lee, Vinitha Balachandran, Dario Poletti
In Phys. Rev. Lett. 120, 200603 (2018), a segmented XXZ spin chain with zero anisotropy in one half and a large anisotropy on the other half gave rise to a spin current rectificati…

Giant spin current rectification due to the interplay of negative differential conductance and a non-uniform magnetic field
Kang Hao Lee, Vinitha Balachandran, Ryan Tan +2
In XXZ chains, spin transport can be significantly suppressed when the interactions in the chain and the bias of the dissipative driving are large enough. This phenomenon of negati…
